Even connected car head units are being targeted by hackers now — experts warn in-car systems are at risk of being hijacked into a botnet

Hackers exploited trusted software updates to deliver malware directly into car head units Kaspersky says this is the first campaign tailored specifically for vehicle head units The malware can run silently without showing drivers any visible interface Car head units are now being drawn into a growi
